Lagoona Lake

Lagoona Lake is a lake with a settlement on the shores where there is a Daycare, Pokémon Center, and a laboratory for fossil reviving and underwater mining. Routes 7 and 8 are connected to Lagoona Lake.

Lagoona Lake Lab
Lagoona Lake Laboratory is located in the centre of Lagoona Lake and shaped like a hemisphere. It is the place for underwater mining and fossil revival. To go underwater, talk to the blonde female scientist in the centre and use an UMV Battery to activate the UMV Submarine inside, which will bring the player to the Lagoona Trenches. If player has run out of batteries, he or she will have to buy more with Robux from that scientist in the following sets:

Meanwhile, the machine at far back is for reviving fossils. Talk to the male scientist next to that machine, and if the player have fossils in his or her bag, player can choose the fossil required, and that scientist will put it into the machine. Within seconds, the fossil will be revived to the corresponding Pokemon.

Lagoona Trenches
Lagoona Trenches is where underwater mining takes place. Player operates the UMV Submarine and clicks on sparkling parts of the wall to start mining. The mining process is nearly identical to Sinnoh Underground in Pokemon Diamond, Pearl and Platinum, only with hammer changed to dynamites, and the pick changed to a drill. Like in real games, if the wall sustains too much damage before treasures are all dug out, the wall will collapse, destroying all treasures that are not retrieved in time. There is a green bar to show how much damage the wall has sustained, and player must dig out all items before the bar fills up.

Each time the player mines, the number of items ranges between 1 to 4 inclusively. The treasures found are also similar to those in Sinnoh Underground, meaning that fossils, plates, certain kinds of evolutionary stones and some rare items can be found, but with the following changes:
 * The 4 fossils found in Unova and Kalos are added.
 * All kinds of spheres are removed.

Day Care
The Pokémon Day Care is a place where trainers can leave their Pokémon while adventuring. After leaving Pokémon at the Day Care, a trainer can then claim their Pokémon later on, along with an EXP increase, level up and new moves if applicable. As in real games, Day Care will not evolve Pokemon, even if the Pokemon has reached the level of evolution. Daycare is also crucial for breeding: if 2 Pokemon of opposite gender are deposited, and both are in the same egg group, the player gets an egg after a short while.

There is also a lady that has received 2 eggs from the Day Care and claims that she cannot raise both eggs, so she offers the player to choose either the white or black egg. The white egg is Zangoose and black egg is Seviper.

Old Rod House
The Old Rod House is the only normal house in Lagoona Lake. The fisherman inside of the house gives players an Old Rod for fishing if they talk to him.

Gift
Player can only choose one of the eggs.

Trivia

 * Lagoona Lake was formed millions of years ago by a meteor. As a result, there are many fossils and minerals, along with some Evolutionary Stones.
 * The name of the lake, Lagoona Lake, may possibly be based off of one of Pokemon Battle Revolution's battle arenas, the Lagoon Colosseum.
